DAVID B. MURDOOH, OF PITTSBURG, PENNSYLVANIA.

FIRE-PLACE.

SPECIFICATION forming part of Letters Patent No. 257,369, dated May 2,1882. I

Application filed February 8, 1882. (No model.) 7

To all whom it may concern:

Be, it known that 1, DAVID B. MURDOCH, of Pittsburg, in the county ofAllegheny and State of Pennsylvania,have invented new and usefulImprovements in Fire-Places, of which the following is a full, clear,and exact descrip- Figure l is a front elevation of myimprovedfire-place, the ash-pit being shown in section.

Fig. 2 is a sectional elevation of the same,

taken on the line mxof Fig. 1. Fig. 3 is a sectional plan view taken onthe line 3 y of Fig. 2, and Fig. 4 is a perspective view of the backplate.

A represents the fire-place, having the ordinary fuel-grates, b.

.0 represents the ash-pit below the fireplace; D D, the dust-finesleading from the space E belowthe fuel-grates up into the chimney F;

and G represents the flue leading from the passage f, through which theashes pass to the ash-pit, up into the chimney. This passage f iscovered with the gratingf, as shown in Figs. 1, 2, and 3.

H represents the metal plate, which is set in the fire-place below thefuel-grates I), and forms the back of the space E, as shown clearly inFigs. 2 and 3. This plate is preferably made with the two squareopenings h h, and is formed or provided with the rims or flanges h itupon the back of the plate, as clearly shown in Fig. 4. These flangesare of sufficient length to reach through the tile J, which forms themain back of the fire-place, so that when the plate is in place theflues D D, which are preferably of sheet metal, maybe inserted fromabove the tile and fitted upon the flanges.

It will be understood that I do not limit myself to metal flues, asfiues or pipes of clay may be used instead; or the flues may be built insolid masonry; but for putting my dust-flues in old fire-places themetal flues are preferred; nor do I confine myself to the employment oftwo dust-fines, as one, two, three, or more may be put in, according tothe size of the fire-place and as may be found most expedient.

The flue G serves to collect and carry away all dust from the ash-pit Oand passagef, as

the ashes drop from the fuel-grate and space E, and the dust-fines D Dcause a draft through the space E, which draws the dust from the space Einto and up through the said fines, thus effectually preventing itsescape into the room. The ash-pit 0 below the fire-place, and thepassage f, leading thereto, serve to keep the space E at all timesentirely free of ashes, so th at the flues D D will at no time beclogged thereby and their action interfered with. In

case the dust-fines are applied to fire-places which have no ash-pitbelow, care must be taken to keep the space E comparatively free from any large bod y of ashes, and the entrances to the dust unobstructed. Bythis construc tion the annoyance due to the escape of fine ashes anddustfrom the fire-place into the room is entirely overcome, and thedust-fines can be applied to both old and new fire-places at a verysmall expense.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination, with the fire-place back,

of the fines D and the plates H, having openin gs hand flanges h,adapted to extend through the tile J, as shown and described.
